An oil with 2,000 ppm calcium performed relatively poorly even with 800 ppm Mo and 770 ppm Ph. Your typical low-SAPS euro oil probably doesn't have more LSPI-suppressing additives than this.

The aging process used was pretty mild as well. It's basically a standard fuel economy test cycle for only 6,000 km, which only dropped TBN from 5.3 to 3.5, so the oil doesn't need to be all that degraded before its LSPI performance suffers.

I see what you see here & that is an interesting test. The theme has been for years now lowering calcium + adding Magnesium is the way to go for now for LSPI. Good post.

The newer ACEA standards have just finally adopted the same LSPI test that has been used for API SP, but the new standards don't cover oils with HTHS >3.5. It might be a while before they update the standards for the thicker grades and add an aged-oil LSPI test.

It does appear that they are targeting more popular fuel saving grades for LSPI which would coincide with GDI engines era. The OEM's are probably deciding which of their specifications they want to use targeting LSPI of which ones I'm not aware of.

There are a couple of studies that have looked at oil viscosity vs LSPI, and there was little to no correlation.

The main risk factor with fuel seems to be its aromatic content, which isn't something you're going to see advertised at the pump. There's doesn't seem to be much correlation between LSPI and octane or ethanol content. SAE 2018-01-1456 is a good study on this.

I'd want to see if they used higher octane fuel as well in that study but good to know they've tested some options already on viscosity alone.

I rly can’t run an oil in my motor that has emission systems protection on the label, but I’m tempted to run this since it’s a pretty thick 30 weight with a nice additive package

I could do without the esp on the label..

Those are good metrics for oil choice.

 

[Redhawk454]

Yes,

Those are good metrics for oil ch

Yes, but i can’t wrap my mind around the emission system protection on the label.. it kinda ruins it for me

date code of 11022G15A 6289 as noted on the jug.

Does this date code mean it was made in July of 2022? If so, this looks like API SN. Someone correct me please.

SP came out in 2020 and Mobil states that it meets or exceeds "API SP ENGINE TEST REQUIREMENTS". What that means in reality is anyone's guess. I assuming that it cannot be labeled as SP due to the additive pack and the fact it does not meet GF-6.

In any event, I can say that it holds up very well in my 2.7TT.

It’s not a guess and yes it is the additive package. There are two parts to the license requirements, a bench test and an engine test. This oil passes the engine test. IIRC the reason it fails the bench test is because it has slightly more phosphorus than what is allowed for an API SP license.

As I have noted before many people would consider this a feature and not a bug. As long as you’re not burning large quantities of oil this is irrelevant in regards to catalyst protection.

I'm curious if the 0w30 SP will look the same as the 5w30 SP version. I'd assume so. New version is much different.

I appreciate the validation. Since the PDS also states that it is "fully compatible with the latest Diesel Particulate Filters (DPF's) and Gasoline Catalytic Converters (CAT's)", I have no concerns about catalytic converter "poisoning", though, of course, my 2.7 is not burning oil.

This is one of the most robust xW-30 oils on the market and I grabbed 100K worth of oil changes. My 2.7 trounced the Motorcraft 5W-30 in only 1K miles, however, ESP holds up very well by maintaining viscosity throughout the OCI.

 

[buster]

This was the SN version from 2020. GTL, PAO, V. It may be the same as this VOA.

From ROC

1) Pour point -62C. Extremely low.
2) Base number = 8.21 mgKOH.
3) Viscosity at 100C = 9.71
4) Flash point = 234C.
5) And oil has a low sulfur content = 0.204%.
6) Sulfate ash content is exceeded. The ACEA C2 standard will limit ash to 0.8%.
7) Infineum additive package.

Considering this for our new Elantra N.

Would make things simple as it’s what I’m already using in our Odyssey.

Only hesitation is the 1700 ppm Ca (LSPI considerations - the Elantra N is 2.0 TGDI).

It passes MB 229.52 which covers LSPI.

What new gasoline 3/4 cylinders - using the correct fuel octane or higher, have LSPI issues?
That's a topic that seemed to slowly die around here the last few years.

Don’t know. But I don’t want to find out!

I experienced some knock a couple of times in my WRX. High gear, low RPM, spiked the boost, then…knock.

Honda 1.5T engines, Accords mostly, have some tendency to blow head gaskets. I don't know the actual failure rate, but it happens often enough to create some internet buzz. And some people claim that using regular fuel in a 1.5T can cause detonation, which damages the head gasket. I've personally not heard engine knock with my Civic 1.5T, but just saying...

Detonation in an ICE isn't caused by the octane rating. Detonation happens after ignition by the spark plug.

Octane is still just as much a factor as insufficient octane means ignition (detonation) can occur ahead of the flame front. Detonation is still an indication of insufficient auto-ignition resistance which is what an octane rating is.

I had not seen anything correlating actual detonation with the octane rating, but I may be mistaken. Not trying to argue but do you have any technical information on that?

 

[fantastic]

Dejavu...
Detonation is described as a premature combustion of fuel, causing knocking (Pre-Ignition). Many of us know that higher octane rating fuel can make fuel less combustible/flammable, in turn reducing (pre-combustion, detonation, preignition, & knocking.)
